At present, most of the notebooks on the market are ultra-thin. In some special occasions, it is necessary to connect multiple different interfaces at the same time. It will be troublesome to repeatedly plug and unplug and change interfaces. At this time, using an expansion dock will be very convenient to use in various application scenarios and improve work efficiency.
Currently, there are USB hub products that can achieve one-to-four performance. With PD chip and USB to RJ 45 chip, one-to-many performance can be achieved. If video/audio transmission is required, VGA and HDMI chips can also be installed to achieve it.
Common interface description
1.USB interface: You can insert U disk, mouse, keyboard, mobile hard disk and charge mobile phones, tablets and other devices.
2.Type-C charging port: Supports PD fast charging protocol, and can be used while charging when using a computer.
3.HDMI interface: The resolution is higher and can support 4K/2K. LCD TVs, monitors, and projectors can all be connected.
4.VGA interface: Many projectors and monitors have this interface, which can support up to 1080P resolution.
5. RJ45 interface: Many ultra-thin notebooks do not have RJ45 interfaces. For people who have special requirements for network stability and speed, using an expansion dock can solve this problem. It can support up to 1000M/2.5G speed.
Due to the convenience of the type-c interface, the mobile phone and notebook fields have gradually unified the Type-c interface. Through these expansion dock conversion devices, the expansion performance of notebooks and mobile phones has been enhanced, bringing greater convenience to the user experience.
